Welcome to Holden Tuning

New Zealand's Leading Mail-Order Holden Commodore Tuning Specialists.

We specialise in giving Holden Commodore's/Ute's/Monaro's from the 1989 VN, right through to the 2006 VZ better throttle response, more Torque, more HP and better economy by updating your cars computer/memcal.

We are about to release a new range of theft-deterrent and dual fuel memcals, as well as some "cam and tune" packages for the 3.8 & 5Ltr models. Please let us know if these interest you.
